Warp3D driver for voodoo 4 on a G-REX

Warp3D for voodoo 4 on a G-REX, does it exist ?

The Warp3D Voodoo 3/Avenger drivers should work if CyberGFX/P96 standards were followed and unless there are bugs. Have you tried simply installing Warp3D and seeing if it works?

I have a G-rex with cybergraphixV4, WarpOS, Warp3D and use Shogo demo to test. My voodoo 3 works fine and shows up in the shogo preferences screen and I can play to warp3D demos but it freezes a lot. So I wanted to test another card... the  voodoo 4 I have. I installed it's drivers with cybergraphix, so far so good, but it's not recognized by Warp3D.

I see Elbox have Warp3D drivers for the voodoo4 on a mediator, but will they work with a G-rex ?

Maybe CyberGFX works differently than P96. Warp3D uses information that it receives from P96 and allocates memory on the card through P96. There is no other card detection that I'm aware of. The Voodoo 4 (VSA-100/Napalm) is backward compatible with the Voodoo 3 (Avenger). I am using the Warp3D Avenger driver with my Voodoo 4, P96 and Mediator 3000T/4000T. I believe there are P96 G-Rex drivers that you can try here:

If I recall correctly, there is a Warp3D environmental variable for the gfx card base register when using Warp3D. Maybe that would help with your setup.

Hyperion code is notoriously buggy. They would rather write new programs than fix bugs it seems. You could try the 68k versions of Warp3D and programs (not Shogo or Wipeout) and see if the same bugs exist. There is a 68k version of Warp3D here that fixes some bugs (and maybe introduces others):

The Voodoo 4 does require considerably more address space to be mapped to the Amiga than the Voodoo 3. I wouldn't think this is a problem with a G-Rex 1200? It is a problem with the Mediator 1200. The special Elbox Warp3D drivers are only used for the Mediator 1200 and are probably specific to the way the hardware maps the memory with the limited address space of the 1200.
